centos 8 install iproute-tc

sudo dnf makecache --refresh

yum install libffi-devel -y

解决centos下安装python3.7.0以上版本时报错 ModuleNotFoundError: No module named '_ctypes'

异常报错

dnf --enablerepo=powertools install oniguruma-devel

参考网址: [centos8 安装 oniguruma-devel](https://www.yanglong.pro/centos8-%E5%AE%89%E8%A3%85-oniguruma-devel/)

解决Please check that your locale settings问题

vim .bashrc

export LC_ALL=C

source .bashrc

还有fzf perl 乱码报错 具体 需要通过centos 8 安装fzf 复现

perl: warning: Setting locale failed.

perl: warning: Please check that your locale settings:

ewomail 新增域名

# ewomail的官方教程里，涉及到多域名的教程其实不完整。

# 他告诉你 从邮箱后台域名栏目添加的域名是副域名，和主域名一样配置解析就可以了

# 但是这里面有一个DKIM，这没说怎么添加

# 生成dkim

amavisd -c /etc/amavisd/amavisd.conf genrsa /ewomail/dkim/201.com.pem

# 在/etc/amavisd/amavisd.conf找到：

dkim_key("a.com", "dkim", "/var/lib/dkim/a.com.pem");

# 在下面新增一行

dkim_key("b.com", "dkim", "/var/lib/dkim/b.com.pem");

找到dkim_key开头，复制添加一行，参考图上。

# 重启amavisd

service amavisd restart

# 对应该域名设置dkim的域名解析即可。
